kernel: remove support for kernel 4.19

We use 5.4 on all targets by default, and 4.19 has never been released
in a stable version. There is no reason to keep it.

-Until upstream commit 6d4cd041f0af("net: phy: at803x: disable delay
-only for RGMII mode"), delays were not disabled on driver probe
-for the Atheros AR803x PHYs, although the RX delay is enabled on
-soft and hard reset.
-
-In addition, the TX delay setting is retained on soft-reset.
-
-This patch disables both delays on config init to align the behavior
-with kernel 5.1 and higher. It can be safely dropped with kernel 5.1.
